For up to r158 you could try the demoduler. For releases above r158 it may work if the source code uses the same style. At least until the WebGL-WebGPU split there is some chance to convert the main three.module.js and some of the addons like OrbitControls.js.

Although this might be an easier approach, a better solution is to use a bundler. Here is a story:

I also have a project that relies to be used by students in a protected environment (i.e. they cannot install other software, and they need to be able to work off-line with local files only). A month ago I converted the software to use Three.js modules, then used a bundler (rollup.js) to pack everything in a single file that can be used locally without internet or local web server. And it works beautifully. But I had two months of trial-and-error nightmares until I did the conversion. And I’m still not sure why it works.

Edit:

Spent half an hour trying to convert one of your nice demos into r179. I think I managed to do it. Attached is a ZIP file that contains:

  • Lens 3D Sim - original.html - this is your original file
  • three.js - modified three.js to be without modules
  • OrbitControls.js - modified OrbitControls to be without modules
  • Lens 3D Sim - external.html - your file that uses these two modified files
  • Lens 3D Sim - embedded.html - your file with embedded modified files

Could you try whether Lens 3D Sim - embedded.html works the way your expect? This should be the single file that works as in the old times.

Here is what it looks like when I start the HTML file from a local folder:

NB. I had to fix the names of few classes, as they have changed, Geometry → BufferGeometry and SphereBufferGeometry → SphereGeometry. All changes are marked by a cat ^..^
